The Waco CG-4 was the most widely used American troop/cargo military glider of World War II. It was designated the CG-4A by the United States Army Air Forces, and given the service name Hadrian (after the Roman emperor) by the British.
The glider was designed by the Waco Aircraft Company. Flight testing began in May 1942. More than 13,900 CG-4As were eventually delivered.
